The present invention relates -to a detonating device, and aims toprovide a novel and improved device of this character arranged in theform of a cane or at the end of a long stick permitting it to be used ina safe manner by children for their lamusement during celebrations andthe like.

Another object of the invention is the provision of a detonating deviceconstructed and arranged so as to explode small caps arranged upon afilm or strip of material, whereby they are automatically fed to firingposition successively, or immediately after the exploding of a capanother will be rapidly advanced to position to be exploded so as topermit the firing of the caps in rapid succession or in a manner tosimulate the firing of an automatic gun or pistol.

lt is also an object of the invention to provide a device of the aboveindicated character, which is simple and substantial in construction,which can be manufactured economically, and which will be thoroughlyefcient and practical in use.

lith the foregoing and other objects in view, which will be apparent asthe description proceeds, the invention resides in the construction andarrangement of parts, as hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimed,without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a longitudinal section through my improved device.

Figure 2 is a side elevation showing the hinged casing swung downwardly.y

Figure 3 is a longitudinal vertical section tallen on line 3 3 of Figure1.

Figure 4 is a fragmentary enlarged elevation of the cap feedingmechanism.

Figure 5 is a fragmentary section taken on line 5 5 of Figure 4, and

Referring to the drawings, it is to be noted that the upper portion ofthe cane or stick 10 is broken away, and that the illustration isconfned to the cap supporting and firing Serial No. 230,790.

mec ianism. The lower end of the cane handle 10 is slightly reduced, asat 11, and extends into an opening or socket l2 in the upper end of thecap supporting and firing body 13. By reducing the lower end of the canehandle 10, a shoulder is provided which abuts against the upper end ofthe body so as to prevent movement of the bodywith relation to the canehandle when firing a cap. Any approved or well known method may be usedfor securing the body 13 to the cane handle 10, such as by passing a pinthrough suchv members or threading the reduced portion 11 of the canehandle into the bdy 13.

rlhe body 13 is provided with an enlarged opening lll which extendsentirely through same from one side to the other, said opening being ofrectangular shape and provided with a shoulder 15 at one side thereofforming the stationary firing surface. The rectangular opening 14Cextends downwardly to one side of the shoulder 15, as at 16, the purposeof which will be set forth as the description proceeds. Extending acrossthe opening la adjacent its upper end is a small shaft 17 for supportinga coiled strip or film 18 having explosive caps 19 thereon. The shaft 17has attached thereto a disk 20 for holding the coiled strip to one sideof the opening 14. In order that the shaft 17 may be rotatably mountedand be removed in order to mount other coiled strips thereon, a smallopening 21 is provided in the body 13 at one side of the opening 111,while in the other side of said opening there is a notch 22 in which isarranged a spring clip 23 for engaging the opposite end of the shaft 17from that received in the opening 21. The spring clip 23 is secured inposition in the notch 22 by meansof a small screw 24, or the like,passed through one end thereof, while the other end thereof is free tobe yieldably forced so as to permit removal of the shaft 17. At thepoint on the spring clip where the end of the shaft 17 engages, saidclip is curved so as to form a slight pocket for receiving the end ofthe shaft 17. The notch 22 is of a width substantially the same as thediameter of the shaft 17 so as to prevent up and down movement of theshaft.

he strip 18 having the explosive caps 19 thereon extends downwardly andunder a pair of spaced apart't'eeding disks 26 having teeth 28 whichextend through pertorations 29 at the opposite edges of the strip orilin, said disks being spaced and fixed to a small collar 25. Byproviding the toothed disks 26 and smallv spacing collar it will beobvious that when the explosive caps pass under the collar they will notbe damaged or ignited. The shoulder 15 on the body 13 has a pair etsmall grooves 30 therein in which the toothed disks 26 pass so as toassure engagement of the teeth'with the strip 18. The disirs and spacingcollar to which they are liXed or integrally connected are mounted on ashaft 31 which extends across the opening 1d at the lower portionthereof and has its opposite end mounted in the bot y 13. At one side otthe spaced disks and rigidly connected to one of said disks is a ratchet32 which is en O'o eed nous by a spring pressed pawl 33 so as to preventvretrograde movement ot the disks, while iigidly carried by the disk 25at the opposite side of the collar is one member ot a clutch 34 whichengages the other member 35 'carried by a gear 36 which is also` mountedon the shaft. A coil spring is arranged about the in the Yoppositedirection, the spring pressed pawl 33 will engage the ratchet 32 so asto prevent Vturning movement ot the disks.

AVfhen the disks are held against movement the angled surfaces ot theclutch teeth will cause the gear to be forced against tension Y ot thespring 37 away troni the reel so that said clutch teethwill not engage.By this arrangement,`the strip 13 having the explosive :caps 19 thereonvwill only be ted downwardly Y i'ioin'the coiled portion of the strip18.

- Extendino verticallv throueh the ouen` D J D i ings 14rand 16, andthrough openings 38 and t1 which is engaged by the lower end of a coilspring42, saidrcoil 'spring being in `nient with the'lower end oi tiiebody 13 at its opposite end. The coil spring will normally hold thesliding bar ll() mits outermost position. Gn one side of the sliding bari0 is arranged a toothed rack bai` 10 the teeth 41 ot which are in meshwith the teeth on the Gear 36. The rack teeth are of greater width thanteeth independent ot the sliding` position of the gear From this it canbe seen 'that when the bar el() is slid in the body 13 the gear 3G willbe rotated. Extendingl through the bar 40 is an elongated slot fl-3which has pivotally arranged therein a trigger del, said trigger beingpivotally connected to the bar l0 by means ot a pin 45. rlhe lower endof the slot 43 only extends pariially through the rod, as at 16, so asto provide a body to which the lower end ot' a leaf spring d? issecured. The leaf spring 47 normally holds the tri ger in posit-ion sothat the upper ond thereof projects slightly to one side oi" the slidingbar 40, the purpose of which will be set i'orth :is the descriptionproceeds. The trigger ll has gradually curved cam surface 43 arranii'cdl elow the point ol' pivot thereof which a 'so normally extends to oneside oli the bar Ll0, and at the side opposite to that which the upperend oi the trigger extends. The gradually curved cam suri'ace i3 is inengagement with an angled surface i9 at one sido ot the opening 33, sothat when the sliding bar d() is forced upwardly against tension ot thespring 42, the tri r will be swung on its pivot so that the upper cnd otthe saine moves .into the bar 40 and is flush with the outer surta/Jo etsaid bar 110.

Also slidably arranged in the body 13 of the device is a hammer 50,which consists oi'f a head 51 and shank 52, said shank being slidable ina correspondingly shaped opening 53 in said body above the opening 1l-.

The lower end portion of the shank 52 as well as the hammer are locatedwithin the opening 14 above the shoulder or anvil 15 and a coil spring54 encircles the shank and is interposed between the head 51, and upperend wall of the opening 14. It will be readily secn that the coil springnormally holds the hammer in its downward posit-ion. The head of thehammer 51 is preferably oi rectangular shape and is of sullicicnt sizeto prevent turningmovement of the hammer in the opening through the bodyof the dcvice as well as prevent it projecting beyond one side thereof,whereby to assure that the trigger la will engage under one end of' thehead 51 to raise the hammer against tension of the coil spring 5d whenthe sliding` bor 4:0 is raised as by contact with the ground.

In order to form a protection l'or the stripped material having the caps19 thercon, a casing 55 is provided having a pair of ears 56 on oppositesides and at the lower end thereof through which a bolt 57 extends, saidbolt also extending through the lower end of the body 13 so as toprovide a pivotal connection for the casing 55. Projecting 'from oneside of the body is a lug 58 provided with a concaved upper surfacewhich is adapted to be engaged by a sprino lip arranged ou thejupper endor' the casing 55 so as to hold the casingin proper position. lVhen itis fil lll)

y ircd to place a new strip in the device, the casing iiiay be .sv/ungupon its pivot so as to gain access to the opening` 111 in the body 13.

ln operation, the casina' 55 is swung' downwardly to the positionillustrated in Figure @of the drawings so as to permit tlie removal oitthe shalt 17'. Said shaft inay be easily ienioved by enertinp,` anoutward pull on 'the end tliereoic engaged by tlie spring' clip llllieiithe sliaiit 1'? ,is reiiioved a roll coniprisiiig tlie strip 1S with theexplosive Caps 19 thereon inay be slid upon the shatt- 1'? and saidshalt placed back iii the body 13 so as to be rotatably supported by thebody. lllie end ot the strip .18 is then passed under the toothed disks26 so that the teeth 28 will project through the periorations Q9 in tbestrip. The casing; may then be sivuneT back to its position and the lue;58 Will liold the saine in closed posit-ion. The device is tlien readyfor operation. By holdings; on the upper end ot the cane handle ors'ielr 10 and pressing the head lll on the slidingbar 4:0 against arigid object, as tlie ground, the bar t0 will be slid Within the body 13and cause the liaiiiiiier 5() to also slide in an upward direction byengagement ot the t loger therewith, the bar l() being),` slid tensiono^ the coil spring' 425 While the liaii'inier is svvi against tensionoit the coil spring' 541. is the bar l0 iiioves upwardly, tlie trigger/l-d which is in engagement with the head oli the hainiiier is graduallyiiioved iiroin engae'eiiient ivitli the head due to the angled surface/lQ on the body 13 and the curved surface Il@ on tlie t 'mj As soon asthe trigger autoinat-ically releases the liaiiiiiier it is returned toits initial position and strikes the explosive cap arrangedtlierebeneath, said cap being@- Xplod-.ed between the stationaryshoulder oi anvil 15 and the head 51 ot the liaiiin'ier. Ars the slidingbar 40 d the hainni'ei' are moved upwardly, the rack teeth. d1 carriedby the slidiiugl bar Ll0 will rotate the gear 36 which will cause thefeedingi dists to also rotate and ifeed a nevv portion olf the ,strip l@liaviin;` an explosive eap 19 thereon t lllllieii pressure is re licvedafter the tiring of the explosive cap, the coil sprino l2 will returnthe sliding?, bar to i itial posuion., and as the saine is returnedinitial position, the spiiiisg1 urged paiv 33 ivill prevent retrogradenioveiiieiit the dislrs due to its engagement with the ratchet 3Q,
